# 1. Status of NetBSD zfs port
NetBSD zfs port is work in progress and can easily panic your system.
**ZFS currently works ony on i386 and amd64!!**
---
# 2. Using NetBSD ZFS port
## Instalation
Use any -current build from i386 or amd64 architecture. All tools and modules should be built by default, now. There are 2 modules used for ZFS solaris.kmod and zfs.kmod. Solaris module provides solaris like interfaces to zfs on NetBSD. The second module is zfs and provides zfs file system functions.
## Configuration
User need to
modload solaris
modload zfs
After loading modules user can create zpool(zfs version of volume manager) and manage zfs file systems on it.
zpool create {zpool name} {type} {device}
where type is:
* mirror
* raidz
* raidz2
* default is normal linear allocation
device is blod device on netbsd /dev/sd0a for example.
zpool create tank mirror /dev/sd0a /dev/sd1a creates mirrored zpool between 2 disk partitions.
With zpool created we can create zfs filesystems or zvols(zfs logical volume disks)
zfs create -V {size} tank/{zvol name} creates zvol with {zvol name} from ZPOOL called tank
Logical disk is created in
/dev/zvol/rdsk/{zpool name}/{zvol name}
/dev/zvol/dsk/{zpool name}/{zvol name}
zfs create tank/{zfs name} create zfs filesystem on a zpool called tank
## Administration
After creating ZVOLS and filesystem they are saved in a /etc/zfs/zpool.cache file and loaded after nextzfs module load.

# 3. Known Bugs
## Show stoppers
### amd64
### i386
### Both
* vnode reclaiming deadlocks
Current code is quite a hack but it works until I will find some time to rework vnode reclaiming on NetBSD.
http://nxr.netbsd.org/xref/src/external/cddl/osnet/dist/uts/common/fs/zfs/zfs_vnops.c#4254
* vnode fsync bug
I think that we are hitting this bug, too. I have some patches in the tree which fixes deadlod in vnode reclaim but after that I'm getting another deadlock in VOP_FSYNC.
## Functional bugs
* Snapshots
* Permissions
* Old code, we should update NetBSD zfs port to new code
* More tasks can be found at <http://nxr.netbsd.org/xref/src/external/cddl/osnet/TODO>
